12:00pm – 4pm (AEST) / 10:00am - 2pm (AWST) / 4:00am - 8am (CEST) / 7:00pm - 11pm, (12 May PDT)
Four peak presentations will showcase state-of-the-art research aimed at speeding up materials design and discovery by integrating artificial intelligence (AI) and machine learning (ML) techniques. Australian and international speakers reveal how large, high quality datasets coupled with machine learning analysis algorithms can play a vital role in the process of new materials discovery. The presentations will be of broad interest for scientists working in the field of HPC/Big Data in materials design and discovery, from advanced graduate research student level, to early career researchers and beyond.

Fueled by our abilities to compute materials properties and characteristics orders of magnitude faster than they can be measured and recent advancements in harnessing literature data, we are entering the era of the fourth paradigm of science: data-driven materials design. The Materials Project www.materialsproject.org uses supercomputing together with state-of-the-art quantum mechanical theory to compute the properties of all known inorganic materials and beyond, design novel materials and offer the data for free to the community together with online analysis and design algorithms. Currently, the Project contains data derived from quantum mechanical calculations for over 130,000 materials and millions of properties. The resource supports a growing community of data-rich materials research, currently supporting over 160,000 registered users and over 2 million data records served each day through the API. The software infrastructure enables thousands of calculations per week – enabling screening and predictions - for both novel solid as well as molecular species with target properties. However, truly accelerating materials innovation also requires rapid synthesis, testing and feedback. The ability to devise data-driven methodologies to guide synthesis efforts is needed as well as rapid interrogation and recording of results – including ‘non-successful’ ones. In this talk, I will highlight some of our ongoing work, including new materials development, synthesis and characterization and associated machine learning algorithmic tools and data-driven approaches.

Dr Ong is also a recipient of the US Department of Energy Early Career Research Program and the Office of Naval Research Young Investigator Program awards.
Machine learning (ML) models have demonstrated human, or even superhuman, performance in many tasks, from playing traditional board games to image classification. Here, I will discuss how ML is poised to have a similar transformative impact in materials science. Applied on large data sets, ML techniques can be used to discover novel technological materials, to model complex systems at an accuracy beyond the reach of traditional computational techniques, and to enhance the accuracy and speed of interpreting characterization data. A key focus of this talk will be on the heterogeneity and scarcity of materials data, the challenges these characteristics present for ML and the potential approaches to overcome them.
Prof. Dr. Amanda Barnard is a Senior Professor at the School of Computing in the Australian National University, the Leader of the Computational Science cluster and the Deputy Director.

Her research has been awarded in 12 national and international awards in 5 scientific disciplines, including the Feynman Prize (Theory) in 2014. She is a leader in the Australasian high performance computing community, and currently serves on the Pawsey Supercomputing Exascale Readiness (PaCER) programme committee, is Chair of the Australasian Leadership Computing Grants Scheme at the National Computational Infrastructure (NCI) and the independent director on the Board of Directors for New Zealand eScience Infrastructure (NeSI).
Materials informatics, and the associated field of nanoinformatics, offer a plethora of new approaches to solving existing challenges in (nano)materials design. These enabling technologies leverage over 50 years of innovation in computer science on machine learning algorithms, and an even longer history of research in statistics to underpin the essential preliminary data science. Provided sufficient appropriate data is available to describe the material or system, new insights can be gained that would be otherwise obscured using conventional experimental or computational methods. Hidden structure/property relationships we can use to inform further research and materials development. Extracting useful insights (such as structure/property relationships) from data analytics and machine learning is however more complicated than simply gathering data and training models, since not all methods are interpretable, and interpretability is essential for decision making. Correlation is also different to causation, and so the importance relationships identified using many machine learning methods are not always actionable. In this presentation we will discuss the differences between conventional modelling approaches and machine learning and demonstrate the advantages of combining a series of different machine learning methods to uncover useful relationships between the properties, structure and processing conditions of graphene oxide nanoflakes.

Materials are at the core of our technological advances, and are needed to address many of our societal challenges: from energy to information, from food to medicine. I’ll highlight the great strides made in the last few years in the design and discovery of novel materials, where computational simulations can now precede, streamline, or accelerate experiments. This acceleration is driven by the central paradigm of computational science (doubling performance every 14-16 months), combined with powerful and predictive quantum simulation techniques, and by the convergence of data mining and machine learning towards materials simulations. I'll also underscore the IT requirements needed to perform calculations in a reproducible, shareable, high-throughput mode. A case study will be our computational exfoliation of all known inorganic materials, leading to ~3,000 promising candidates, for which I will discuss some highlights for quantum spin Hall insulators and superconductors.
